Added a bunch of patches from Benjamin Bannier for Pythia libraries

(bug #230673), ruby name changes (bug #236072), opengl include files
(bug  #236071), extra documentation (bug #236070). Also added a reflex
flag to  enable users encountering bug #233698, some emacs changes
thanks to ulm. Finally, added some patches from upstream documented in
http://root.cern.ch/twiki/bin/view/ROOT/PatchesV5-20-00.
